Q: Is the Loud Mouth really one of the best things I can do to my bike?

The Loud Mouth makes as much performance as $2000 in bolt-ons. It's proven, patent pending technology and it will keep dirt from entering your engine. Filter maintenance so easy that you'll save 20 minutes to an hour per weekend on filter changes. As a rider, the air filter is the number one thing you work with and the most important part on your bike. You might as well be happy when you pull your seat off after a long day of riding.

According to the Magazines -- Transworld Motocross' Editor, Don Maeda, says, "The Loud Mouth is the best thing you can do to your bike for under $200" and Motocross Action listed the Loud Mouth as a Top 35 Product: "Cleanest Intake ever built (Guaranteed to Make You Faster)".

The proof is in the pudding.

Q: How do I install a Loud Mouth on my bike?

Most of the Loud Mouth Intake Systems install by removing the hardware on the front of the air box which is typically 5 or 6 8mm nuts. For example, the Kawasaki KXF 250/450s have 5 nuts and 1 screw. Once the hardware is removed, you can pull the stock thumb screw configuration out of the air box. The gasket and hardware supplied in every Loud Mouth Kit allows you to quickly install the Loud Mouth Intake into the air box and without sealant (although, it couldn't hurt to add some). You do not have to remove the subframe on most bikes if you have an 8mm wrench and a 1/4 drive 8mm socket for removal of the stock assembly.

Q: Do I have to modify my airbox?

Most of these intakes can be installed in as little as 20-30 minutes with ease. Some bikes require that you trim uneven tabs incorporated into the intake boot. You can do this in a few minutes with a razor and you can always re-install the OEM setup. Since most bikes have a removable thumb screw filter cage, you can swap out the OEM setup with the Loud Mouth without modifying the air box. The Fuel Injection CRF 250/450s however, are the exception. We supply an installation template and instructions that allow you to easily drill the 5 holes in the air box.

Q: Do I have to re-jet or change my bike's mapping with the Loud Mouth?

No. We've never had to remap with the Loud Mouth after installation. The bikes take to the perfected airflow. As far as jetting is concerned, it's extremely rare that our riders/customers have jetting issues after installing the Loud Mouth on their bikes. In fact, it's so rare that we don't even bring jets to the races when we're installing them. On the dyno, the Loud Mouth always moves the air/fuel mixture in the right direction; carburetor and FI alike. We have seen these systems fix jetting issues and eliminate bogging. In the rarest of cases, we suggest correcting extreme jetting issues that may already exist prior to installation.

Q: Can I use my regular air filters with the Loud Mouth?

No. Fortunately, we supply every kit with a filter. The clamp-on air filters are manufactured specifically for the Loud Mouth Intake Systems and adapt differently than the OEM. The cage-less design allows for quick filter changes and a perfect seal locking dirt out from the intake tract.

Q: Does the Loud Mouth remove the screen?

Yes. The Loud Mouth is a very simple system. Intake (flange on housing) and clamp-on style filter. It eliminates the thumb screw, cage and OEM filter reciever. The filters manufactured by Twin Air and No Toil are flame retardent. According to these companies, a non-petroleum-based filter oil is recommended. Avoid petroleum-based solvents, gasoline, mineral spirits etc..

Q: How much do extra filters cost?

The price of a replacement filter varies: No-Toil: $32.99 Twin Air: $36.75

Q: Which increases power more, this or the K&N airfilter?

This unit is nice! Everyone says something different on power. It varies on so many diff factors. In general K&Ns breathe better than a tacky foam filter, but not always. Also, intake systems and air box mods are going to yield far more power gains than filters alone. This system with a foam filter made 1 Horsepower more than a K&N on the Dyno on a 2012 YZ 250F. Riders claim that the Loud Mouth made their bikes run better than anything else they've ever put on their bike.

Q: Will this still work good with stock exhaust or would it make my bike run bad?

The performance gains we have seen from the Loud Mouth Intake are consistant on every bike, stock and mod. You'd be suprised how well your engine runs when you have a Loud Mouth to get the air in, regardless of the exhaust.

Q: Do you have to oil these filters?

Yes. Treat them like any other foam filter.
